Abstract

Dichtungsanordnung zum Abdichten von zwei relativ zueinander hin- und herbeweglichen Maschinenelementen (1, 2), umfassend eine Stangen- oder Kolbendichtung (3), die in einer in Richtung des ersten Maschinenelements (1) offenen Nut (4) des zweiten Maschinenelements (2) angeordnet ist und aus einem Dichtring (5) und einem Vorspannring (6) aus elastomerem Werkstoff besteht, wobei der Dichtring (5) einen im wesentlichen T-förmigen Querschnitt aufweist und mit der Dichtfläche (7) seines Radialstegs (8) die abzudichtende Fläche (9) des ersten Maschinenelements (1) dichtend berührt, wobei der Vorspannring (6) unter elastischer Vorspannung zwischen dem Nutgrund (10) der Nut (4) und dem Axialsteg (11) des Dichtrings (5) angeordnet ist. Der Übergang von den Stirnseiten (12, 13) des Radialstegs (8) zu der Dichtfläche (7) ist gerundet ausgebildet.
